10 Claims, 3 Drawing Figures DEVICE FOR ADJUSTING THE POSITION OF ANARCHERY BOW ARROW REST BACKGROUND OF THE INVENTION This inventionrelates to a device for adjusting the position of an archery bow arrowrest, by which the arrow rest can be adjustably moved in and out of theside of the archery bow, permitting the archer to select a desiredposition of the arrow with respect to the archery bow. Further, thedevice has a shock-absorbing arrow support so as to absorb the shockcaused the instant when the arrow is released.

It is true that an archer can hit the target accurately by practisingthe proper techniques from nocking to releasing. As a matter of fact,the hitting rate can be improved by practising the proper method forshooting an arrow so far as the, bowsight and the arrow rest aredisposed at a mostsuitable location for the archer. However, there areoften cases where the location of the bowsight and the arrow rest withrespect to the bow is not suited for the archer, and this becomes acause of hindering the improvement of his techniques.

In shooting an arrow, it is known that such factors as the diameter andlength of the arrow, the length of the archers arms, etc., delicatelyhave to do with the direction of flight of the arrow. The arrow isusually fixed to the bowstring with the direction of the arrow slightlydeviated from the center line connecting. the center of the target withthe bowstring or the center of the bow, and when released the arrowflies depicting a very slight waving line. With what an angle to theabove mentioned center line the arrow should be fixed to the bowstringdepends on the archers proper conditions and the condition of the arrowitself.

Therefore, it is very important for the archer how to set the anglebetween the center line and the fixing direction of the arrow, and it isvery convenient to the archer if the angle can be adjusted as desired,depending on the archers own condition and the arrow condition.

Further, the shock caused the instant the arrow is released from the bowhas muchto do with the hitting rate of the bow and arrow.

SUMMARY OF THE INVENTION One object of the present invention is toprovide an adjustable arrow rest device for an archery bow by which thearrow rest can be adjustably positioned in and out of the side of thebow. i

Another object of the present invention is to provide an adjustablearrow restdevice for an archery bow which effectively absorbs the shockcaused when the arrow is released from the bow. 7

Other objects, features and advantages of the invention will be apparentfrom the following description, taken in connection with theaccompanying drawings, in which the figures show and embodiment of theinvention. It is to be expressly understood, however, that the drawingsare for the purpose ofillus tration and description only and are notdesigned as a definition of the invention, reference being had for thispurpose to the appended claims.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 2 is a side viewof the adjustablearrow rest device shown in FIG. I; and

FIG. 3 is a front external view of the adjustable arrow rest device.

DESCRIPTION OF THE PREFERRED EMBODIMENT A movable member A, which isformed substantially in the shape of a short cylinder, is embeddedslidably in a recess or room la formed in the handle section I of anarchery bow on the side of a sight window 2. The movable member A has anupper section Al and a lower section A2. The upper section A] has athreaded through hole 3. One mouth of the: through hole 3 that islocated near the sight window 2 of the archery bow is narrower than theother mouth thereof. From the broader mouth, a damper shaft 5 having adiskshap'ed base 6 is inserted into the hole 3 together with rubberbuffer pieces 7, 7', with the base 6 interposed between the pieces 7 and7'. Thereafter, a screw 23 is tightly screwed into the broader mouth ofthe through hole 3, so that the base 6 of the damper shaft 5 is held inthe hole 3 with a proper resiliency. The resiliency may be properlyadjusted by tightening or loosening the screw 23. To the outwardlyprojecting erid of the damper shaft 5 is attached an arrow supportingplate 4 by means of a screw or other suitable means, the arrowsupporting plate 4 serving to determine the set position of an arrowindicated by a dotted circle 8 in FIG. 1. The lower section A2 of themovable member A is formed into an inner-threaded cylindrical projection10 of an appropriate length extending from the sight-window side of thebow 1 towards the opposite side thereof. A rhomboidal plate member 13 isattached to the sight window side of the movable member A by means of ascrew 14, which is screwed into the inner-threaded lower section A2 ofthe movable member A, that is, the threaded through hole 9 of the lowersection A2. The

plate member 13 is provided with an arrow rest 12 projecting therefrominto the sight window 2 of the arlindrical porjection 10 of the movablemember A so that the projection lO may be slidably guided in the throughhole 24. This stationary member B also has a guide 15 disposed on theinside wall thereof. The guide 15 is fitted into an elongated slot orgroove 11 formed on the outside wall of the lower section A2. The guide15 runs in the lengthwise direction of the lower section A2. This guidepermits the sliding movement of the lower section A2 within the throughhole 24 of the stationary member B and prevents the lower section A2from rotating.

From the through hole mouth of the stationary memberB opening at thatside opposite to the sight window side of the bow, is: inserted anouter-threaded shaft 19 of a control member C, the shaft 19 beingthreadedly engaged with the threaded through hole 9 of the lower sectionA2 of the movable member A. The control the movable member A and theside wall 17 of the stationary member B, is interposed a coil spring 16in a compressed state, the coil spring 16 constantly urging the lowersection A2 towards the sight window side of the bow, thus absorbing aplay between the threads of the inner-threaded lower section A2 andouterthreaded shaft 19. The knob 18 is provided with a screw 22 at theperipheral wall thereof, so that the tightening of the screw 22 enablesthe control member C to be locked on the outwardly projecting endportion of the stationary member B.

As is apparent from FIG. 2, the plate member 13 has two horizontallyparallely extending elongated openings 20 and 21, into which the screw14 and the damper shaft 5 are inserted, respectively.

The method of operation for the adjustable arrow rest device for anarchery bow of this invention is as follows. If an archer has found itnecessary to move the arrow rest towards or away from the bow, he onlyturns the knob 18. Further, if he finds it necessary to position thearrow rest closer to or more away from the bowstring, he only loosensthe screw 14 and moves the plate member 13, horizontally along theopenings and 21. As the movable member A provided with the arrowsupporting plate 4 and the arrow rest 12 can be moved horizontally byturning the knob 18, an archer can regulate the lateral position of thearrow supporting plate 4 and arrow rest 12, as desired, by means of theturning knob 18. The device of this invention can achieve a very finepositional adjustment of the arrow supporting plate and arrow rest,since the back-andforth movement of the movable member is carried out bythe threaded engagement of the lower section A2 and shaft 19.

Once a desired position is determined through the abovementionedoperations, it can be maintained by tightening the screws 14 and 22.

From the foregoing description, it will be understood that the presentinvention provides the adjustable arrow rest device for. an archery bowwhich improves the hitting rate with the archery bow, as the adjustmentof the position of the arrow rest can be achieved easily and the shockproduced at the time of release of an arrow is absorbed and reduced bythe rubber buffer pieces through the damper shaft. Further, the deviceof the present invention is simple in construction and is easy inoperation, and moreover, it is excellent in stability as the position ofthe arrow rest does not shift unless the knob of the control member isturned.
